Choosing A Van To Convert


Choosing a Van For Your Conversion

Luckily, there are more choices these days for a van to use as a base for you conversion.  This page provides a little detail on some of the choices.


The Full Size Euro Vans

In the last few years, the van designs that originated  in Europe from Mercedes, Fiat and Ford have become available in the US.  They offer full standing height and a relatively efficient design, and have become popular for RV conversions — both DIY and commercial.  The Nissan NV van is less popular, but offers about the same inside dimensions.

Some dimensional information on the RAM ProMaster, Ford Transit, and Mercedes Sprinter for comparison:


The information above is from the Sportsmobile site — a great source of information on custom van conversions.

Lots of back and forth on which of the above is the best choice for a base van.  A good place to get first hand information from the owners are the online forums:

I’ve found the information and discussions on these forums to be very helpful.

Compact Euro Vans

Vans such as the Ford Transit Connect and the RAM ProMaster City offer a more compact and  higher mile-per-gallon choice for a conversion.  Its more of a challenge to get a good functional camper into these smaller envelopes, but there there are many successful conversions out there — some examples…

I have seen pictures of Transit Connect conversions with a pop-top to gain headroom, but don’t know if he pop-tops are available in the US?

There are also a number of European conversions based on the VW van, but the VW van does not appear to be offered in the US at this time.

US Vans

US vans such as the Ford Econoline appear to be fading out, but could be used as the base for a camper conversion.  Bear in mind that they are less efficient (lower mpg), and without an add on pop-top they will not offer full headroom.




  1. I purchased a Ford Transit 350 D. Building the walls has been a real pain in the ass. I am not sure but the Sprinter seems to be an easier build. It seems most the conversions companies use the sprinter because I think they think it is easier to convert. what do you think

    • Hi,
      Mine is a ProMaster, so I’m not too familiar with the Fords or Sprinters.

      One thing I do like about the ProMaster is that the walls are pretty close to straight up and down which probably makes things a bit easier. Boxy shape makes the conversion a bit easier.

      I wish that someone would come out with a set of exact templates for the wall and ceiling pieces so that you would not have to go through all the careful measurements and trail fitting of each piece. I’d definitely have paid for such a set of templates.


  2. I could be wrong, but that data on the PM on the SPortsmobile site seems wrong regarding the length of the PM LB… not 22’2″, but 20’10″… and internal height is 6’4″, not 6’2″, right?

    • What — I got the data off the internet — how could it possibly be wrong:)

      I’ll check it out when we get home from this trip and correct it then — thanks!


  3. Thank you so much for this website/forum. Hope you can organize a live seminar/training, I will attend even with a fee.



  4. Hey thanks for the great website. I’m looking to start my van life and need to pick the right van. I’m a taller guy with long legs any idea which van would be more comfortable to drive?

    • Hi Will,
      I think you will probably have to just go sit in the ProMaster, Transit and Sprinter vans. I see pro and con comments on seating comfort for all of them, but just not sure on the tall with long legs comfort for each.

      You will also have to evaluate the standing head room in the back, but the diagrams above should be helpful for that. And, if you want to sleep crosswise, the ProMaster is a few inches wider than the others.
